Sorry to bother with what seems like a stupid question. But I bought a Samsung with an 8750m in it. But the OS (win 8) is using the Intel 4000 graphics. I would like to at the very least be able to confirm that the AMD card is even in the machine. I installed GPU-z but could not see the 8750m.

When I go into the device manager its only shows Intel hd 4000 in the "display adapters" category. One more thing. Under the "Other devices" category it says video controller. Could that be it? Windows can't seem to find drivers for it. I open up the properties for it and it says in the resources tab. "This device isn't using any resources because it has a problem."

The box says the card is there in the specs list, and the AMD radeon sticker is on the machine.

Is there a diagnostics I can run?

interesting results... usually the gpu is on a separate heatpipe/sink than the cpu, so it shouldn't have much of an impact on the cpu temps. Secondly while 3dmark has a cpu test in it prime95 should put harder load on the cpu. The laptop might use the same heatpipe(s) to connect...

lol yes sorry guys it is a laptop. Don't want to open it because if I need to return it I don't want them to think I was doing something to void any kind of warranty. Also should I get the drivers from samsung or amd website? drivers might be the problem but I think its weird that windows cant even find a general vga driver for it.

so here are the scores I got. pretty bad. Something is acting fishy with the card. out of the links given to me by Avocade I was able to install the "Latest Beta Driver".

mark 11:

mark 06:
http://www.3dmark.com/3dm06/17494665
On the 3dmark06 I noticed it read my memory as 32mb.

So weird things I have noticed.
AMD catalyst control center Doesn't have any of the setting I am supposed to have.
When I used the above amd driver link (64-bit), and installed the Driver Verification Tool It gives me the error "Catalyst Mobility cannot be downloaded due to incompatible hardware/software"
Next when I run GPU-Z it says the name of my card is "AMD Radeon HD 8600/8700" and will not give me any real details like gpu clock speed, bandwidth, memory type ect....

Have you checked in the BIOS if there is an option to disable the Intel HD graphics or some other settings for the hybrid graphics mode? (just for the troubleshooting)


Also the highest reported cpu turboclock on those 3dmark scores is pretty wierd so maybe the cpu is throttling because of heat or something...
so check the CPU load temps, download RealTemp or some other

So I did what you said and found myself at leshcatlabs.net I guess they do custom drivers. after a morning of those drivers conflicts with openCL I just formatted my hard drive, reinstalled windows 7 (x64) and installed the custom drivers once again. I ran far cry 3 and it seems to do all right. plays on ultra with a solid FPS. Im going to take a guess that the intel iGPU can't do that? Skyrim wants to still force me to play on low.

So now when I load up GPU-Z it still will not tell me core clock speed or memory ect. And the drive used is still "AMD Radeon HD 8600/8700" instead of 8750m like it should say. I won't be picky about that, just something to note.

I ran 3dmark11 again:

Everything its starting to check out except what Kari had mentioned. That really concerns me. Why does the turbo speed drop so low. I downloaded and ran RealTemp during the 3dmark11 tests and my maximum temp hit 90c/92c is that normal? What can I do to prevent that or fix it? and lastly are there any good cpu benchs I should run?

the maximum allowed temp is 105c (Tjunction)

At that temp the cpu will shut down, so it is a bit extreme reference point. I'm not sure of the actuall temp limit where throttling starts but you might be very close to it at those low 90s...

I'm guessing this laptop is quite new so there shouldn't be much if any dust in the heatsinks yet, so the only thing you could do is to make sure the airvents arent blocked by anything so it can 'breathe' (both intake and exhaust) and that the fan ramps up under load properly... frankly it should sound a bit like a hair dryer at those temps :D

You could take look at the actuall real time clocks with TMonitor
http://www.cpuid.com/softwares/tmonitor.html
and use Prime95 to put some serious load on it
http://www.guru3d.com/files_details/prime95_download.html
And keep the power brick plugged in so it doesn't do any power saving tricks

If it crash'n'burns the cpu heatsink might not be mounted properly at the factory or something else is wrong with the cooling system...

I downloaded prim95 and tmonitor. Completed the stress test. No big flashing alerts popped up during so I assume it didn't crash and burn. max CPU temp was 81c/82c. It appears everything went smoothly. white testing I'm sure it wasn't using the dGPU, so less heat. Maybe combined with the dGPU and the CPU at max it was to much heat for it? anyway.. I'll be buying a cooling pad soon enough. Would taking it apart and applying good thermal past help as well?

Secondly while 3dmark has a cpu test in it prime95 should put harder load on the cpu. The laptop might use the same heatpipe(s) to connect both chips to a single finstack so the combined heat results in higher temps like you suspected. Still, during the graphics tests the cpu isn't stressed much and vice versa...

If the laptop uses the same cooling system for both chips it makes reapplying the thermal paste more difficult since you'd need to do them both... But it should bring down the temps at least few degrees with some really good paste if succesfully applied (maybe 5-10c). I suppose you could at least open the case to take a look what it looks like inside and what should be removed etc to actually get to the chips themselves, and then decide if you'd feel comfortable doing it.

Oh what clocks did the cpu use while prime was running? Did it use the advertised turbo?

during the "SX Bench" my speed clocks in at 3182 MHz. Using Prinm95/Sensor tests through realtemp, it maxes out both cores at what looks like 2.9.

ok, sounds about right.
